A shredder is provided for shredding agglomerated metal scrap from a machining process. The shredder includes a rotatable shredding tool mounted on a drive shaft that is rotated using conventional power transmission devices. The axis of the shredder drive shaft is approximately in-line with the drive shaft of a feed device that delivers metal scrap to be shredded to the rotating shredding tool. The shredding tool is rotated so that the teeth of the shredding tool tear against the leading edge of the agglomerated metal scrap. Optionally, fixed hooks are located on one or both of the feed device and the shredder housing for engaging the agglomerated metal scrap. Where fixed hooks oranchors are used, the rotating tool engages the agglomerated metal scrap and spins the metal scrap against the fixed hooks, thus causing further shredding to occur. The shredding tool may be spring-loaded for axial movement in such a way as to allow it to move away from an object that causes it to jam. Also, alternatively, the shredding tool is reversibly rotatable, and the shredding tool teeth are oriented so that the shredding tool kicks away and unjams when reversibly rotated. In one form, the teeth on the shredding tool are flexible finger-like members that extends axially toward and engage the metal scrap as the scrap is output from the feed device.
